The two Mi-17 V5s are currently in the factory in Kazan, RF, and will be transported to Serbia aboard an airplane in June, the daily Blic is reporting.
The transport helicopters can carry up to five tons of cargo and up to 30 soldiers, or 12 wounded persons on stretchers.
This model is an iteration of the Mi-8 that has been manufactured since 1967, and has had many modernized versions.
